将数据网格设置为每页仅显示 5 行
我正在使用 DOJO 进行数据网格演示
<div id="grid_log" dojoType="dojox.grid.DataGrid" store="log" structure="window.layout_log" queryOptions="{deep:true}" query="{}" clientSort="true" rowsPerPage="5"> </div>
，但问题是 grid_log 每页不只显示 5 行。这个标签有什么问题吗？为什么忽略 rowsPerPage="5" ？
I am using DOJO for data grid presentation
<div id="grid_log" dojoType="dojox.grid.DataGrid" store="log" structure="window.layout_log" queryOptions="{deep:true}" query="{}" clientSort="true" rowsPerPage="5"> </div>
but problem is that grid_log doesn't show just 5 rows per page. What is wrong with this tag ? Why ignores rowsPerPage="5" ?

看起来 rowsPerPage 值不是“查看”的页面，而是“虚拟”页面。也就是说，网格一次仅呈现其自身的一部分（为了提高非常大的数据集的性能），并且 rowsPerPage 值用于确定一次呈现多少行。
如果您滚动到网格上渲染页面之外的位置，它将根据需要进行渲染。
如果您显示的行数超过 5 行（由于您在网格上设置的高度），则将 rowsPerPage 设置为 5 只会导致可视部分一次批量渲染 5 行。即，将有一个查询以 start=0 和 count=5 调用您的数据存储，并发送另一个以 start=5 和 count=5 的查询，依此类推 - 直到呈现所有可见行。
但是您可以在此 页面 上看到 - 这是带有分页的网格示例。也许它对你有帮助。
It's look like the rowsPerPage value isn't pages that are "viewed" - but rather, "virtual" pages. That is, the grid only renders portions of itself at a time (in order to improve performance for very large data sets) - and the rowsPerPage value is used to determine how many rows to render at a time.
If you scroll to a position on the grid that it outside the rendered pages, it will render it on demand.
If you are displaying more than 5 rows (due to the height that you have set on your grid) - then setting rowsPerPage to 5 will just cause the viewable portion to be rendered in batches of 5 rows at a time. i.e. there will be a query called to your datastore with start=0 and count=5, and another query sent with start=5 and count=5, etc - until all the visible rows are rendered.
However you can see on this page - it is example of grid with paging. May be it helps you.
就新的 dojo 而言，dojo 1.7.2 这里有分页功能，可以在页面中为增强的数据网格设置。如果这是您想要的，则必须从新的 dojo 导入分页插件并设置它在网格中。您可以设置网格中的页面
As far as new dojo is concerned dojo 1.7.2 here you have the pagination feature where in the pages can be set for the enhanced datagrid.If that is what you want that you will have to import the pagination plugin from new dojo and set it in the grid.You can set the pages in the grid
